Abstract Background Forest succession is an important ecological process and has been studied for more than a century. However, changes in nitrogen (N) availability during succession remain unclear as they may lead to either N saturation or N limitat

Abstract Background Conifers partition different N forms from soil, including ammonium, nitrate, and dissolved organic N (DON), to sustain plant growth. Previous studies focused on inorganic N sources and specific amino acid forms using 15N labelling

Abstract Identifying the mechanisms that structure niche breadth and overlap between species is important for determining how species interact and assessing their functional role in an ecosystem. Without manipulative experiments, assessing the role o

Societal Impact Statement Increasing atmospheric nitrogen (N) deposition represents a major global change factor, but its long-term effect on tree growth and carbon (C) sequestration remains uncertain. Our manipulation experiment and meta-analysis re

Climate and roots, not hyphal development, influence carbohydrate sharing from broad-leaved trees to ectomycorrhizal fungi under elevated CO2

Background To assess the extent of belowground carbon transfer to ectomycorrhizal fungi in natural forests, we used δ13C and loge C/N measurements to calculate spatial dynamics of carbon movement into ectomycorrhizal sporocarps. Methods Fourteen bro
